- — Second Matt Anderson[src]
The second Matt Anderson was a dishevelled and minorly injured exact copy of the original Matt Anderson. He appeared to Matt in the Anomaly Research Centre shortly after the team had stopped New Dawn. He told Matt that he had to "go back", before mysteriously disappearing. (Episode 5.6)
- Although next to nothing is known for certain about the second Matt, many theories have been put forward by fans regarding who he is. The most common theory is that he is Matt's future self, sent back from the new future to warn Matt about it; but some fans have also speculated that he could be a clone or twin brother of Matt, or just a hallucination.
